SPECIFICATION forming part of Letters Patent No. 662,843, dated November 27, 1900. Application filed January 27, 1900. Serial No. 3,052. KNO model.)

$0 a/ZZ whom, t may concern:

Be it known that I, SEEN P. WATT, a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gas Generators or Lamps, of which the following is a specification. v

My invention relates to acetylene-gas lam ps or generators, whether of the portable or stationary type,V but more particularly to the carbid-holding cup or receptacle.

My Objectis to provide such a cup of novel construction for the perfect distribution of the water and for the ready charging with carbid, as well as for the ready removal of the residue. The cup is so constructed that it" can be charged with the carbid and can be carried apart from the lamp into which it is insertible.

While I have herein shown my invention as applied to a bicycle-lamp-that is, a lamp of the portable type-it will be understood that my invention is applicable to lamps of the stationary type, such as house-lamps, dto.

In the accompanying drawings, Figure l is a sectional elevation of a lamp with the carbid-cup in place therein; Fig. 2, a perspective of the Water-distributer; Fig. 3, a side elevation of such distributer; Fig. et, a top plan of the distributer, and Fig. 5 a perspective of the upper end of the carbid-cup.

Inasmuch as my invention relates only to the generating means of a gas-lamp, more particularly to the carbid-holdin g receptacle,the other A parts of the lamp will not be described in detail. Such parts are well known and also are non-essential to the invention herein.

The lamp shown as embodying one exempliiication of my invention in a complete device comprises a suitable casing l, having a Water-chamber 2, a generating-chamber 3, a flame-chamber 1i, bottom cap 5, and suitable passages between such chambers. A tube 6 communicates with the water-chamber and projects downward into chamber 3, Where .it has at its end a plug 7, forming a valve-seat regulated byavalve 8. Agas-outlet passage 9 leads from the generating-chamber3 to the burner-tip l0 in the dame-chamber. A carbid cup or holder ll is inverted and closed by the cover l2. The cup preferably7 has a tube 13 extending above and below its closed end and surrounding the valve-seat S. This tube has a side slot 26 and forms a Water-guide and a gas-passage. The running of the slot the full length of the tube prevents the formation of a water-veil and the consequent iiuctuation in the dow of the water and gas.

The water-distributer is fiat at its lower portion and extends diametrically7 across the cup. Itis composed of two plates lain close proximity, except at the top, or of a single perforated plate bent upon itself at the lower end. Consequently when in this case, and particularly in the claims, there is used the expression two plates in close proximity, or substantially such expression, it will be understood that a single plate thus bent upon itself is included. The separate top ends l5 of the plate are spread laterally and are circular in plan View. One or both plates may (though not necessarily) have an impression or cavity 17 near the central top portion, just below the central tube 13, from which cavity two impressions or grooves 1S may lead toward the lower or bottom corners ci' the distributer. The plates are covered on the outside-that is, next to the carbid-with linen 19 or other suitable material both for causinga distribution of the water and preventing the entrance of carbid-dust into the perfoi-ations of the plates, as well as providing a ilterin g medium for the gas. The vertical edges 20 of the plates may be turned over upon the linen to clamp it, and such linen may also be extended over the top of the ends l5 and clamped against the top innersurface of the cup, as hereinafter referred to.

A disk 2l, having a downwardly-extending marginal flange 22, is adapted to be received by the carbid-cup and to be removed therefrom. This disk is of the saine diameter as the cup and its edges fit closely against the internal surface of the cup. This disk has a central opening 23, through which the tube 13 passes when the distributer is in place. This anged disk forms the means of attachment for the distributing-plates and also provides the means for readily withdrawing the residue, thereby cleaning the cup. The upper or spread portions of the distributer-plates are formed or out to the inner diameter of IOO the disk, into which they are pressed, the turned-over portions of the fabric or covering 24 on top of the plates being clamped against the inner surface of the disk, as shown in Fig. l. To make a rigid connection between the plates and the disk, these parts may be soldered together, as at 25. The construction shown provides a perfect and uniform distribution of water, and the generated gas cannot escape from the cup without passing through the covering of the distributer, whereby aperfect filtering or straining of the gas is obtained. In charging, the carbid-cup is filled and the cover put on, whereupon the cup is reversed and then replaced in the lampcasing. The Water admitted by the valve will drop upon the plates and will be distributed uniformly by them to the carbid. The grooves or channels 18 will permit of the same amount of distribution to the lower portion of the cup as to the upper portion, so that uniform distribution of water is assured. When it is necessary to remove the residue and recharge the cup, the bottom cap 5 is unscrewed and the entire cup removed, and the cover l2 is taken off, whereupon the lower end of the distributer can be grasped by the fingers and Withdrawn, together with the disk 21, thereby forcing all the residue from the cup, which will be clean and ready for another charge. Inasmuch as the disk fits closely within the cup, it will scrape along the sides of the cup and thoroughly clean it of all residue. The construction shown provides for the ready cleaning and recharging of the device. Moreover, the cup is dust-proof and can be carried loaded and apart from the lamp. As shown, lthe cup has a single opening, through which the water is admitted and f rom which the gas escapes. After the water-valve is opened the lamp will Work automatically, since the gas pressure will regulate the amount of water permitted to feed through the valve.

Although I have described more or less precise forms and details of construction, I do not intend to be understood as limiting myself thereto, as I contemplate changes in form, the

proportion of parts, and the substitution of equivalents as circumstances may suggest or render expedient and Without departing from the spirit of my invention.

While I have herein shown and described the cup and disk as cylindrical or circular, it is to be understood that I do not limit these parts to that form and that obviously they may be of any other form.
